Sonic is a good movie

[floramon]

Where did Tails come from?

In the beginning, the Guardian never mentioned about Tails.

During the whole movie, Sonic kept saying that he IS ALONE!!!!! He has NO friends!!!!

But, after the movie ends, in ester egg, Tails suddenly appeared and said "I must help Sonic before it is too late."

Clearly, Tails knew Sonic, and he also knew how to find Sonic.

So, why Sonic never mentioned about Tails during the 1 hour and 40 minutes?

Why Sonic never tried to locate Tails when he was in trouble, or lonely?????

Where was Tails hiding at the time?

Why Tails suddenly appeared from out of nowhere?
